I think I can answer this use case - can you not just use CQL filters?
e.g. you could use the filter "validstart DURING
2006-11-30T01:30:00Z/2006-12-31T01:30:00Z"
The syntax is explained here:
http://docs.geotools.org/latest/userguide/library/cql/cql.html

Can't answer this one though - if you find a solution to this please
let me know!
I believe there's a plugin for NetCDF (i.e. lovely 3d raster standard)
for GeoTools but I don't think this has been integrated with
Geoserver.
